I HAVE A 91 GTA WITH HEDMAN 68470 AND THE HEADERS ARE
RIGHT UP AGAINST HITTING THE A/C BOX,I HAVE A FREIND
WITH A 91 Z WITH THE SAME PROBLEM.DOES ANY BODY STILL
HAVE A/C WITH THIS PROBLEM?AND WHAT DO YOU DO?
AND I WANT MY A/C TO WORK.

 

I tried to install headers today and ended up smashing the **** out of my AC box

 

I have Dyno Don's Headers, so they are probably a bit different, but I was also having problems w/ the A/C box. They definately rubbed and made it difficult to get in. I had put the headers on the motor before I put the motor in the car. When I go the motor in, the header was touching the A/C box. It eventually got a bit of space between when the motor mounts and tranny mounts were seated all the way. I have new Poly motor and tranny mounts, and there is not a lot of room, maybe 1/4-3/8 of an inch now with everything seated. Hopefully it's enough where the heat won't melt the box.

 

The Edelbrock TES headers I had didn't rub but the heat from the headers did a number on the box. This is what happened trying to take the a/c box out when switching to a standard heater box.

 

i have hedman mid tubes on my car. and when we installed them i was thousand of an inch from the ac box. wheww... but in the end. i still ended up removing the ac box. made a plate for the big hole... and now my msd box sits there.

 

I CAN'T BELEAVE THEY DONT MAKE A HEADER TO WORK WITH AC,
HOW CAN YOU DRIVE IN TEXAS WITH OUT AC.?
